STORM SASH CONSTRUCTION Application led November 12, 1930. Serial No.495,123.

An object of my present invention is to provide a storm sashparticularly adapted for mounting on a window equipped with a rollingwindow. screen. Still a further object is to provide a storm sash ofsimple, durable and inexpensive construction consisting of a two partsash, each part having a vertical flange along one side for fitting intoa slit opening of a rolling screen guide whereby to support the stormsash relative to a window frame which is equipped with a rolling windowscreen.

Still a further object is to provide the flanges on the storm sash ofconsiderable width so that they can have sliding movement relative tothe rolling screen guides for thus allowing for expansion andcontraction and inaccuracy of dimensions or misalignment and yetproviding a weather seal between the o window frame or the rollingscreen guide thereon and the storm sash to prevent the entrance of coldair. i

Another object is to provide a top flange on the storm sash engageablewith the rolling screen construction for providing a weather seal alongthe top of the storm sash.

Still a further object is to provide a means for mounting a storm sashof this construction on a window frame which is not provided with arolling window screen.

Another object is to provide a fastening means between the two parts ofthe storm sash forconnectingthem together edge to ,edge and constrainingthem to engage a stop mounted on the window sill and to also engagealong their upper edges with the rolling v.screen construction. Withthese'and other objects in view my invention consists in theconstruction, ar,- rangement and combination of the various parts of mydevice, whereby the objects contemplated are attained, as hereinaftermore fully set forth, pointed out in my claims, and illustrated in theaccompanying drawings, in

On the accompanying .drawings I have used the reference numeral 10 toindicate a wall. A window opening is formed in. the wall and is definedby a sill 12, side jambs 14 and a head jamb 16. The window opening isscreened by a rolling screen 18 rolled on a shaft 20.

The shaft 20 has its ends journaled in the ends of a rolling screen box22 which constitutes a casing for the screen 18 when rolled up. Acontrol bar 24 is Secured to the free edge of the rolling screen 18 andis provided with a finger ledge 26.

Rolling screen guides 28 of tubular construction are inserted in theside jambs 14 and are adapted for the edges of the rolling screen 18 tobe guided therein, these edges extending through a slit opening formedin each guide 28. An alignment block 30 is formed on each end of thecontrol bar 24 and these are slidable in the rolling screen guides I28.

The foregoingdescription refers to a roll` ing window screen of generalconstruction and forms no part of my invention. I merely utilize thetubular rolling screen guides 28 with their slit openings for thepurpose of supporting my storm sash construction without in any wayaiie'ctin the operation of the rolling window screen itself.-

My storm sash construction includes a pair of storm sashes B havingframes made preferably of metal although they can be made of wood orother construction and transparent coverings 32 of glass or the like.The frame of each sash B includesv a bottom rail 34, side rails 36 and38, a top rail 40 and where necessary, one or more intermediate crossrails 42. Theglass 32 can be retained in position by any suitable means,such for instance as by means of retainer members 44 held-in position byscrews 46. Putty isl indicated at 48 for sealing the joint between theframe and the glass.

Each side rail 36 terminates in a flange 36a while a weather seal jointis formed between the side rails'38 as shown best in Figure 2. rlhisjoint consists of an angular flange 50 on one rail 38 and achannel-shapedfiange 52 on the other rail 38. The bottom rails 34 areadapted to rest directly on the window sill 12.

The top rail 40 of each storm sash B terminates in a channel shapedflange 40a. The flange 40a is adapted to partially encircle or cover thelinger ledge 26 of the control bar 24 and the free edge of the fiange isadapted to contact with the control bar as shown in Figure. 3. As shownin Figure 8 the lower iange of the portion 40a is cut away as indicatedat 54 to clear the rolling screen guide 28. As shown in Figure 7 theupper flange of the portion 40a is cut away as indicated at 5 6 to clearthe aligning block 30.

A weather proof joint is formed between the channel-shaped flanges 40aof each storm sash B as shown in Figure 8. A filler member 58 is securedto one of the flanges 40a and overlaps inside the other one. 4A portion58a of the filler member 58 covers the upper end of the channel-shapediange 52 to prevent entrance of air at this point.

A stop 60 for the lower ends of the storm sashes B is mounted on thewindow sill 12, the control bar 24 serving as a stop for the upper endsof the sashes. A fastening means is provided for the sashes which may beof any suitable type, but preferably one which has a tendency to drawthe bars 38 of the sashes towards the stop 60 and the control bar 24. Ihave illustrated a fastening means which will accomplish this purposeincluding a mounting plate 62 secured to one of the rails 38 and amounting plate 64 secured to the other one.' Headed-studs 66 are securedto the mounting plates 62 and 64. A locking plate 68 is pivoted on a pin70 carried by the mounting plate 62. A handle 72 is provided for thelocking plate 68.

As shown in Figure 5, the locking plate 68 is of obtuse angle formation.As shown in Figure 6, the portions of the plate 68 adjacent the slots 74are slightly slanting. It will v thus be obvious that when the handle 72is rotated in a clockwise direction the ends of the locking plate 68 arewedged beneath the headed studs 66 producing a tendency for the sashes Bto bend in the same direction as the ends of the locking plate 68 andthereby constraining the rails 38 of the sashes B toward outwardmovement and consequent engage-- ment at their lower and upper ends withthe stop 60 and control bar 24 respectively.

As shown in Figures 9 and 10my storm sash construction can be used on aWindow frame which is not equipped with rolling window screens. ln placeof rolling window screen guides, channel members 76 are provided on theside jambs 14 into which the flanges 36a of the sashes B may beextended. A flange 7 8 may be embedded in the head jamb 22 with whichthe channel shaped fiange 40a of the sashes B may coact. The members 76and 78 may be embedded in the j ambs or mounted thereon after the Windowframe is made, if desired. v

Practical installation In the installation of my storm sash constructionthe control bar 24 is first moved to its upper limit of movement and theleft hand sash .B placed in position. The right hand sashB is thenplaced in position, the sashes originally assuming the position shown indotted lines in Figure 2, after which they are swung to the full lineposition. The tubular portions of the screen guides 28 allow forswinging movement of the flanges 36a therein wherebyl the sashes may bereadily installed.

After the fastening devices are manipulated the sashes are retained intheir proper poy sition with the flanges 40a covering the linger ledge26. To remove the storm sashes from the window the operations justdescribed are reversed.

The installation for the type shown in Figures 9 and 10 is the same asfor the type made especially for windows equipped with rolling screens.The ianges 36a, it will be noted, substantially fill the slit openingsof the rolling screen guides 28 and therefore form an effective weatherseal at this point.

The flange 40a covering the linger ledge 26 provides a weather sealjoint at this point and the weight of the sashes B hold them firmly downagainst the Awindow sill. Felt packing or the like can be provided alongthe lower edges of the sashes if desired.

It will be obvious that the storm sashes can be readily installed afterthe rolling screen 18 is rolled up'and can be as readily taken downwithout in any way affecting subsequent operation of the rolling screen.The flanges 36a coact with the guides 28 in such a way that they do notdamage them and yet an efficient joint is formed at this point whichwill allow for contraction and'eXpansion be- E,

- whereby cause the flanges can move relative to the guides 28 aconsiderable distance before being pulled out of the guides.

My construction eliminates the necessity of providing any specialfittings for lnounting a storm sash on a window frame which is equippedwith a. rolling window screen. It thus overcomes an objection heretoforeraised in connection with rolling screens in that especially on hingedtypes of windows there is no place on the outside for installing a stormwindow and the rolling screen is in the wav on the inside. l

ome changes may be made in the construction and arrangement of the partsof my device without departing from the real spirit and purpose of myinvention, and it is my intention to cover by my claims, any modifiedforms vof structure or use of mechanical equivalents which may bereasonably included within their scope.
